In my case i found a bit more simple solution, i think. We use Liquibase for database migrations, so here i made a conditional migration only to be run on H2, where i change the column type to H2's "other" type. With the other type, H2 just stores it in the database and doesn't think twice about how the data is formatted etc.

The SQL and PL/SQL Data Type column contains all possible data types. The Ora cle Mapping column lists the corresponding Java types that JPublisher uses when all the type mapping options are set to oracle.These types are found in the oracle.sql package provided by Oracle and are designed to minimize the overhead incurred when converting Oracle data types to Java types.

Introduction to SQL BLOB. BLOB (Binary Large Object) is a data type in standard SQL used to store large amounts of data. It is basically a binary string of variable length, stored as a sequence of bytes or octets. BLOB data type is generally used to store large files such as images, media files such as video and audio clips in the database.

There is no such data type in the SQL Standard and such data type is quite exotic even for general purpose programming languages. I don't see any good reasons to have it in H2. These numbers are usually stored in two columns or as a character string value.
